Sand Tank Filter Installation Sand tank filters are very simple to install and maintain, requiring only a screwdriver, wrench, PVC glue, and sealing tape to seal the plastic unions. 1. The sand tank filter should be placed on horizontal concrete or a solid surface with comparable hardness. In addition, the location where the sand tank filter is installed should be convenient for the connection of pipelines, the operation of the control valve and the maintenance of the sand tank filter. 2. Filling of the filter sand, the filter sand should be filled from the upper opening of the filter.
(1) Loosen the nut and remove the filter control valve (if the control valve has been installed); (2) Cover the mouth of the plastic pipe with a plastic protective cover to prevent filter sand from entering; (3) Refill the filter Before sanding, we require that half of the clean water be injected into the filter cavity, which acts as a buffer and prevents damage to the cylinder and internal devices when the filter sand is put in. (4) It is required to fill filter sand of correct grade and weight (20# silica sand). in the middle of the filter cavity, then remove the guard. 3.

Pay attention to align and insert the central tube in the filter and the hole at the bottom of the switch; (2) ) Tighten the nut with a wrench to connect the control valve and the filter; (3) Install the pressure gauge (with sealing ring) at the screw hole of the control valve body, do not overtighten.
4. The nozzle marked "PUMP" on the valve body is connected to the water pump, the pipe returning to the swimming pool is connected to the nozzle marked "RETURN" on the control valve, and the nozzle marked "WASTE" on the control valve is connected to the sewage pipe. 5. Connect the water pump separator to the water inlet of the water pump, and install the water pump suction pipe. 6. For the connection of the water pump power system, the water pump should be equipped with a suitable leakage protection switch.
